You can create a new file, for example, named setup_repo.sh, and then add the following contents to it:

Prerequisites

  1. Install Git and configured
  2. Create a GitHub account.
  3. SSH access set up for GitHub.

Script 

    
      #!/bin/bash
      # Add a title to the README.md file
      echo "# prueba" >> README.md
      # Initialize a new Git repository
      git init
      # Add README.md to the staging area
      git add README.md
      # Commit the changes with a message
      git commit -m "first commit"
      # Rename the default branch to main
      git branch -M main
      # Add a remote repository
      git remote add origin git@github.com:UserName/prueba.git
      # Push changes to the main branch of the remote repository
      # And set it to track the upstream branch
      git push -u origin main

  1. Make sure to grant execute permissions to your script by running:

         
       chmod +x setup_repo.sh

  2. You can then run the script from your terminal with:

       
     ./setup_repo.sh

This script assumes you have Git configured and SSH access set up for GitHub. Adjust the GitHub repository URL if necessary.
